Nitrogen fluxes from treefrogs to tank epiphytic bromeliads: an isotopic and physiological approach
(Springer, 2010-04-01)
Diverse invertebrate and vertebrate species live in association with plants of the large Neotropical family Bromeliaceae. Although previous studies have assumed that debris of associated organisms improves plant nutrition, ...
Factors controlling plankton community production, export flux, and particulate matter stoichiometry in the coastal upwelling system off Peru
(Copernicus Publications, 2020)
Eastern boundary upwelling systems (EBUS) are among the most productive marine ecosystems on Earth. The production of organic material is fueled by upwelling of nutrient-rich deep waters and high incident light at the sea ...
Influence of Intensive Agriculture on Dry Deposition of Aerosol Nutrients
(Soc Brasileira Quimica, 2010-01-01)
A procedure is presented for quantification of sources contributing to atmospheric aerosol chemical nutrient concentrations and dry deposition fluxes. Source apportionment using principal component analysis (PCA) and ...

Viral-Mediated Microbe Mortality Modulated by Ocean Acidification and Eutrophication: Consequences for the Carbon Fluxes Through the Microbial Food Web
(Frontiers Media, 2021-04)
Anthropogenic carbon emissions are causing changes in seawater carbonate chemistry including a decline in the pH of the oceans. While its aftermath for calcifying microbes has been widely studied, the effect of ocean ...
Eutrophication effects on CH4 and CO2 fluxes in a highly urbanized tropical reservoir (Southeast, Brazil)
(2021-01-01)
Shallow urban polluted reservoirs at tropical regions can be hotspots for CO2 and CH4 emissions. In this study, we investigated the relationships between eutrophication and GHG emissions in a highly urbanized tropical ...
Environmental Characterization of a Eutrophicated Semi-Enclosed System: Nutrient Budget (Encerrada Bay, Tierra del Fuego Island, Patagonia, Argentina)
(Springer, 2009-11)
Encerrada Bay (EB) is located in the far south of Argentina, on the north coast of the Beagle Channel and is artificially connected with Ushuaia Bay (UB). This study was carried out between 2004 and 2005; and assesses the ...
Bromeliad-living spiders improve host plant nutrition and growth

Bromeliad-living spiders improve host plant nutrition and growth
(Ecological Soc Amer, 2014)
Phosphorus release from sediments and the role of oxygen and trophic state
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA SANITÁRIA, 2018-04-13)
Phosphorous (P) is a limiting nutrient of algal growth. Reducing input of point P sources of
surface waters, although essential, is not enough towards mitigating eutrophication due to the P
internal loading. There are ...
